Our detailed step-by-step guide continues below…
How To Brush Finish Outer Tube Joints – Step 1: Preparation
Abrasive Tip: Set your machine speed between 3000 and 4000 RPM – this will avoid burn marks and maximise disc life.
Dress the grit of your new disc by gently grinding a test piece of metal. This will reduce the initial aggression of the disc when using it on your workpiece.
How To Brush Finish Outer Tube Joints – Step 2: Sanding The Weld
Move the RCD back and forth lengthways along the tube, ensuring that the sanding lines follow the original grinding pattern of the stainless steel.
Abrasive Tip: Sand at an angle of 10 to 15 degrees using light pressure – this is very important when producing a high quality brushed finish.
Continue using the disc up to the area in which the rounded outside corner meets the hollow inside corner. Continue until the corner where the tubes meet is sharp and round, and the outside corner is blended into the inside corner.
You can then repeat this step with the SAG/5/125 unitised disc if needed.
How To Brush Finish Outer Tube Joints – Step 3: Restoring The Brushed Finish
Simply cut a 10cm section from the FMGRT/AF/60040 Tex belt and manually smooth over the section between the inner and outer corner of the tube joint.
Then, using the remaining longer section of belt, manoeuvre this backwards and forwards over the length of the tube as far as the corner. This step is crucial for blending the rest of the stainless steel with the corner you are focusing on.
Repeat this step on the other side.
Abrasive Tip: You can easily make the finish more coarse or fine by using a different grit belt; we have a selection here.
How To Brush Finish Outer Tube Joints – Step 4: Cleaning Up
To protect the tube from grease and fingermarks, you will need our Inoxiclean spray.
Spray this over your workpiece and remove with a soft microfibre cloth to reveal the clean, brushed finish.
